Car runs great except it has constant miss at idle. I need info on the best way to isolate it. What should happen if I unplug MAF while engine is running and is there s way to test MAF
THANKS in advance as always

I'm sorry, forgot to mention miss fire is why I changed plugs, wires, cap and roter. The car has been doing this since I got it almost 4 years ago, 2000 miles ago. It's not that bad but I want to fix it. I don't know how smooth it should idle. I did have a brand new 89 I ordered in 89 but I don't remember how it idled

Reason: Wording
A miss is usually caused by a spark plug not firing (or firing at the wrong time). Pull all the plugs and check for one wet one. That will be the one that is not firing.
